I have always used foxpro callers. I currently have a FX5 caller. I'm trying to learn to use mouth calls. There are a lot of callers on the market that will get the job done. Find one that has the features you want. Look around and see if you can find a used one. Lots of people buy a caller and quit after going out a few times.

If you buy a foxpro let me know. I will make you a list of some must have sounds.

I have hunted Hogs in Culpeper county and have done pretty well with it.
